Phanteks showed off premium versions of its latest Glacier C300-series CPU water blocks, with the Glacier C350iP and the Glacier C350AP. The two are nearly identical to each other, but differ with their CPU socket support, with the former supporting Intel LGA115x and LGA2011(v3)/LGA2066; and the latter supporting just AM4. These blocks themselves are identical to the Glacier C350-series, but come with acetal tops. The gunmetal-gray top replaces the clear-acrylic ones on the standard C350-series blocks, such as the C350a and C350i. The cold plate material is still nickel-plated copper, with mirror finish at the base. Both blocks are priced at USD $69.99, which is surprisingly $10 cheaper than their acrylic twins.
